Issue with combined commands

[mersox]

Hi all. On the OpenBOR manual, it says that:

cmd {sequence of inputs} {freespecial#}
    ~{sequence of inputs} now accepts "+" to add mutiple commands. Examples:
a + a2
u + f a

I have this line on my character file:

com u freespecial1
com u + f freespecial2
com f freespecial3

The engine "crashes" if the second line is present. It works fine if I delete it. So it seems it's not accepting the "+".

I have tried with multiple OpenBOR releases including the latest one I could find, 4469. It states:

Fatal Error in load_cached_model, file: data/chars/winston/winston.txt, line 18, message: Invalid freespecial command

And by the way what is up with taking away the option to type "palette none"?
